Established at the Nene Valley Railway, Wansford, England in November 2007, the principal purposes of the society are to:
Support the restoration of rolling stock of The Compagnie Internationale des Wagons-Lits et des Grands Express Europeens, owned by and based at the Nene Valley Railway, currently restaurant car 2975 and sleeping car 3916, both practically and financially.
Promote and develop a Museum facility, to be called the 'Night Mail' to display the carriages and associated artifacts, in conjunction with the Nene Valley Railway TPO group.
Collate both historical and current day information on the company Wagons-Lits, its carriages and artifacts, making the information freely available on the web site, in publications and in the future museum facilities.
Promote the world wide preservation of historically important railway rolling stock and artifacts.
